Gender in health and safety in NZ Hi all, currently NZISM membership is 49.6% female and 50.4% male. Our stats change regularly as we grow our membership. Earlier this year, for the first time we had more female members than males which reached a peak of 53.7% females. In the lead up to this peak we generally sat at about 45% female to 55% male. But with a good portion of the profession amongst our members I am confident that the current 50/50 split represents the market.
